General Comments. ( Brief data summary and scan listing )
EJ007B had 9 stations, 4 8MHz IFs, and two polarizations. There were 16 frequency points per IF/pol, and integration times were 4s. Considerably more information is included in the experiment's cover letter on the standard-plots portion of the EVN Archive. In the pipelining, only J0927+3902, J1050+3430, J1130+3031, J0730+4049, and 3C286 were fringed. The SOLINT was 2.0min.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.918 . ERI* = 0.918 . The ERI was 0.918. The losses include both Mc & Ef having field-system problems, each for a ~2hr period, with an overlap of 1hr, plus Tr loss of IF2,RCP throughout the whole experiment.

Plots of the autocorrelations .
Comments.
240 pages, each scan plotted separately, all stations

Plots of the uncalibrated amplitude and phase against time .
Comments.
16 pages, full-experiment for Jb-* baselines, no calibration applied. Each 4s integration plotted separately. The fringe-finders dominate the amplitude scale.

Plots of the uncalibrated amplitude and phase against frequency channel .
Comments.
240 pages, scalar averaged Jb-* baselines, each scan plotted separately.

The uncalibrated amplitude and phase of the crosshand correlations against frequency channel .
Comments.
120 pages, scalar averaged Jb-* baselines for Stokes=LR, each scan plotted separately.

TSYS against time .
Comments.
TY1 table, each IF/pol on a separate plot. Tr IF2,RCP plot corresponds to a "dead" channel.

Telescope sensitivities from the a priori TSYS and Gain curves (the square of this number gives the antenna noise (SEFD) in Jy - the smaller the better).
Comments.
gain amplitude from CL2 table

Fringe-fit phase solutions (including Parallactic Angle correction).
Comments.
CL3 station phase solutions -- CL3 = CL2+SN2, thus also includes the initial amplitude/parallactic angle calibration from CL2 and the fringe solutions from SN2. Tr's high rate is eveident.

Fringe-fit delay solutions .
Comments.
SN2 station delay solutions for the fringed calibrators, each IF/pol on a separate plot. Tr plot descends from +40 to -40 ns. Tr used a Rb frequency standard throughout the session instead of the usual H-maser.

Fringe-fit rate solutions .
Comments.
SN2 station rate solutions.

Telescope bandpasses .
Comments.
bandpass table 1. Only 3C286 was used for bandpass calibration.

Calibrated amplitude and phase against time (a priori amplitude calibration and fringe-fit solutions applied).
Comments.
Jb-* baselines calibrated with table CL3 -- ampitude scale still dominated by fringe-finders; more phases seen lined up ~0.

Calibrated amplitude and phase against frequency channel .
Comments.
240 pages; Jb-* baselines calibrated with CL3 and BP1.
